s'rA'NT Jones: Jaoounr a citizen of the Republic of France,'residingat 5Boulevard near Paris,

de la Seine, Neuillys'urseine,

Erance, have invented certain new and usean Improvements in or Relatingto the y for Vehicles, of which. the following is a specification,-reference being had therein to, the accompanying drawing.

This invention relates to an elastic spring support for motor cars andother vehicles adapted, to resiliently-connect the frame of the. vehicleto the spring proper, and has for its object to 'produceashbck absorberor ,deadener, wh ch will be "simple in ,con-

struction," certai'n in action, comparatively hich may. be readilyadjustd and substituted for the usual hangers ,on the various-gkinds ofvehicles now'inuse, without it being necessary to' modify any pieceorportion of the mechanism now employed, or to make a single hole or any.otherchange in said hanger mechanism With-these and other objects inview, the invention consists in thelnovel details of construction andcombinations, of parts more fully hereinafter disclosed and particularlypointed out in the claims. ,7

Referring to the accompanying drawings forming apart of thisspecification in which like parts in all of the views z-Eigurel is a"front elevational in section of a shock absorber comprising doublespring boxes madein accordance with my invention, and which may for thevarious hangers now employed on vehicles in gen eral; Fig. 2 is aside-elevational. view partly in section, of the parts shown in Fig. 1;Fig.- 3 is a frontelevational view partly in-section of. a slightlymodified construc-' tion ada ted for French cars, in which a rigid roprojects from the frame; and, Fig. 4 is a-side elevational view alsopartly in section of the'elements shown in Fig. 3. Referring moreparticularly to Figs. 1 and'2, my elastic spring support, or shockabsorber comprises a plurality of cylinders or boxes 1, each providedwith a closed head 4, through which passes the bolt or pin 8 ca tingmovements of my invention,

of the hanger member 2 supported fromthe bodyfof the car.- Inclosed insaid boxes or form, and supporting each 'sprin is a, .U-

shaped rod 5, screw-threaded atits ends and provided with the nutsr9,adapted 'to" support a l3 npon.which thelower .of said springs 3 1'estI;Theupper loop portion of said rods 5 pass of the flat vehicle-spring "7,

and said bolt 6,, as showm I It results from the 'contsruction nowidis-A. CORPORATION or cases 1, are springs 3 preferably helicalin' over the.bolt- 6 while the. bolt "8 is straddled by sa'd rods and aspa'ce- 16. 7is provided between the top or saidf-heari4 closed,that any weight whichmay be trans} a mitted by the member 2 to thebolt 8, will the heads 4,casings 1 and latter in turn will cause tend to depress springs 3. Thesepressure to be transmitted tothe nuts 9' and bolt 6, thereby 2 with th'e'spring 7 by -a resilient shock absorbing device. It will also beobserved that the head t is provided with an up-' wardly extendingportion to receive the bolt 8 and that the rods 5 passthrough thisextension as well as through the head proper, thereby being providedwith long connecting the member bearings capable of steadying therccipros the boltsG and 8 owing to the space 16.

It, therefore, follows that substantially all strains will be directedmatter in what positions x. be found. Consequently, I there will belittle tendency for lateral wear,

longitudinally oi the casings 1 no said casings may in the said longbearings,,and the rods 5,

but also saves the car. the bottom of body of dimensprings when enrouteand nofnewfspr-ing' is to behad. In such case the. nuts 9"may be quicklyscrewed up until the two broken convolutions rest firmly upon eachother,

when the journey may be then resumedfwith the unbroken 'ieonvolutionsdlfis a' simple matter to re- 7 take out the springs and,

share of the work, and thereby preventing the other unbroken spring 3frombeing destroyed by an'overload.

. Another most important feature of my invention resides in itscapability of being placed on almost any make of car. That is to say,the extreme ends of the members 2 and springs 7 through which the bolts8 and 6 respectively pass, vary'in width on different makes of car. Bymounting the casings 1 entirely independent, however, I can readilyplace them in position no mat-. ter what the dimensions of these partsmay be, by simply lengthening or shortening the said bolts 6 and 8. 'Inother words, my shock absorber can be readily placed on al-- most anytype of car in a few minutes without boring any holes, or cutting anyparts whatever, even though the hanger elements may widely vary.

In Figs. 3 and 4 I have shown a construction of shock absorberespecially adapted for French cars, which are usually provided with arigid rod 20 of the general shape shown, supported from the chassis 10.I prefer in thismodification to employ a single casing 1, and to connectthe rods 5 with a U-shaped piece 21 which receives the bolt 6 of'thespring 7 as illustrated. Otherwise,the,structure is the sameas in Figs.1 and 2. 14 in all the figures shows a con venient means for connectingthe hanger member 2 or 20 to the chassis. What I claim is 1. In anelastic spring support the combination of a hanger member; a boltcarried by said member; a casing closed at one cndwith a head throughwhich said bolt passes and open at the other end; a spring 1n saidcasing; a U-shaped rod supporting said spring at its open end, andpassing through said head near its looped end; a second bolt passingthrough said looped end; and a vehicle spring carrying said second bolt,substantially as described.

2. In an elastic spring support the combination of a hanger member; abolt carried by said member; a casing closed at one end with a headprovided with an extension through which said bolt passes and open atthe other end; a spring in said casing; a U- shaped rod and disksupporting said spring at its open end, and said rod passing throughsaid head and extension near its looped end;'a second bolt passingthrough said looped end leaving a space between said second bolt andextension; and a V0 hicle spring carrying said second bolt,substantially as described.

3, In an elastic spring support for vehicles, the combination of ahanger member;

spring carrying said second bolt, substan-.

tially as described.

4. In an elastic spring support for ,vehicles, the combination of ahanger member; a bolt carried by said member; a plurality of casingseach closed. at one .end by a head.

having'an extension through, each of which said bolt passes, and open attheir other ends; a helical spring in each casing; a U

shaped rod in each casing provided with nuts supporting said springs,and passing through said heads and extensions near their looped ends; asecond bolt passing through the looped ends of each of the U- shapedrods; and a vehicle spring carrying said second bolt, substantially asdescribed.

5. In an elastic spring support the combination of a hanger member; abolt carried by said member; a casing closed at one end with a headthrough which said bolt passes;

a spring in said casing; rod members sup-.

porting said spring, and passing through said head; a yoke attached tosaid rod members; a second bolt passing through said yoke; and a"vehicle spring carrying said second bolt, substantially as described.

In testimony whereof I afiix my signatur in the presence of twowitnesses.
